You need to be good "friends" with goth girl and mama hogg, then , go to the diamond thing in your manager suite, and check everything ( Aspiration skillsect....) and when you close it, If ur a boy, u get Jed.b 's overalls, and if ur a girl, u get Ava Cadavra's goth outfit ( but it will also change ur hair so save first, and then try the outfit on so u dont get stuck with the other hairdo)
